Specification of vLetters Patent.

`Patented Nov. 9, 1909.

Application led December 22, -1908. Serial No. 468,815.

' which the following is a specification.

- are pivoted to admit the is for the purpose of enabling the assemblingvof .these cylinders and also for My invention relates to improvementsin means for increasing the available recording surface in phonograpl1s,and it consists in the constructions, combinations and arrangementshereinafter described and claimed.

An object of my invention is to provide a phonograph in which a recordsurface of a flexible nature and having a relatively great length -Inaybe insertedor removed, and in which the bearing members for the cylinderment of the record. y

A further object of my invention is to provide a record applicable to acylinder type, in which the virtual diameter of the record is greatlyincreased, while the actual diameter is not.

Other objects and advantages will appear in the following specificationand the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, in which-Figure l shows an end view of a phonograph containing one embodiment ofmy invention. Fig. 2 shows a side view thereof, and Fig. 3 is a planview.

'In carrying out lmy invention I provide a lframe A in which'issupported the upper feed rollenB having a flange bX on one end and alower roller C', having a similar flange c". These rollers are journaledin the bearings 'b and bx and aand c", respectively, carried by theuprights of t-he frame The bearingsb and c are elongated as shown in 'Fig. 2 in order to support their respective shafts when the cone bearingsBX and The cone bearings bx and 0X are hinged to one of the uprights ofthe frame A atby and cy, respectively,and may be locked atV th oppositeends bz and cz, as clearly shown in Fig. 1. This construction slippin onthe flexible record D.. u g

The flexible record D is preferably an endi, less band composed of anysuitable material removal or replace- Cx are removed from the ends ofthe` shaft.

which will permit a bending of the band or belt such as the films` ofmoviiw )icture mavcorrespondi]1g to the height of the frame A.

A longer belt would be used with a correspondingly higher frame. thusgiving a greater record surface. 'lhe belt may be ot' any width, butinpractice I find it preferable to use a belt with a virtual diameter ofthirty-six inches and a width of six inches on a feed cylinder ofapproximately live inches in diameter. After the belt is slipped on, theslack may be adjusted lo the proper degree by a movement of the upperpart of the frame relatively to thelower or by a movement of thebearings of one of the 1ollers. The roller C may be of any convenientdiameter and 'serves merely as an idler.

The diaphragm E may be any standard diaphragm andis preferably supportedby means of the arms e and e. The arm e is provided with a guide sleevec2 arranged to travel back and forth on the guide rod F. The arm c onthe opposite side is provided with a feed member G arranged to coperate-with a feed screw H. The feed roller B may Y be driven by ineans of abelt (not shown) ruiming over a drive pulley K, by any "suitable power.Thefdiaphragm may be provided with the usual horn or sound intensilierL.

From the foregoing description of the various parts of the device theoperation thereof may be readily understood. When the machine isassembled in the manner already indicated and the needle is placed atone edge of the continuous band, the rotation of the feed cylinder 5will cause the belt 9 to move under the needle and the action of thefeed screw will cause the needle to be shifted Alongitudinally of thebelt. It will thus be seen that with a feed cylinder, say of five inchesdiameter, the effect of ane-ndless belt traveling over said cylinderwill be' that of a cylinder of a virtual diameter equaling that of thebelt, thereby giving a much larger record surface without much increasein the feed cylinder. Of course the feed screw Il may be made to advancethe needle transversely of the belt, z'. e. longitudinally of the feedcylinder at any predetermined rate.

Byusing a record belt of a virtual diameter llO of thirty-six incheswith ninety-six threads upon the feed screw for every inch in length ofthe feedcylinder (or width of the belt), we will oly -ain a recordhaving a length approximately sixteen times the length of the ordinarycylinder record. Used at the saine record speed of the ordinary-cylindermachine, it will require nearly fifty-eight minutes time to reproducethis record.

In the effort to make phonographs of com! Vparatively small size butwith large record surface for use in connection with motion pictures, 1twill beat once apparent that this device furnishes a means forovercoming the obstacles in connection with the recording,

or rather reproductiolnof long speeches to correspond with, oraccompany, the actions v of the characters in the motion pictures. So

alsoan opera of considerable length may be recorded by means of amachine equipped with my invention.

While I have shown this device as consisting of a ame of a special form,it will be understood that any. frame suitable for the esaeo arranged inthe other end of said frame,

hinged bearings for said feed roller and said idler, a flexiblerecording surface carried by said feedvroller andsaid idler, saidrecording surface consisting of an endless belt arranged to run on bothof said rollers, and

va st lus arranged to engage said recording sur ace.

2. In a phonograph, a frame :provided with upper and lower stationarybearings, a feed roller mounted in said upper bearings,

an idler mounted in said lower bearings,

upper and lower hinged bearings carried by said frame and arranged toswing into alinelment with the respective upper and lower stationarybearings and a flexible recording` ysurface carrled by sald rollers.

In a phonograph, a frame provided with upper and lower vstationarybearin s, a shaftl having a guide flange on the end o the rolleradjacent the stationary bearing, a lower shaft journaled in said lowerstationary bearing, an idlerearried by said lower Y shaft and providedwith a flange on the end adjacent the stationary bearing, and upper andlower hinged bearings carried by said frame and arranged to swing intoalinement with their respective stationary bearings and adapted toengage the ends of the' upper and lower shafts respectively.
